Bob,
Another option, if you're still interested, would be Gauge Mate gold chamber adapters. The gold version stays in the chambers, and uses the ejectors to extract the spent shells. I have the 16-20 version. They pattern very well, and mine only weigh 1.2 ounces for the pair. That weight between the hands will not affect balance of the gun. You can find them and order at
www.gaugemate.com. I believe the cost is $169.99 plus shipping.
Otherwise, reloading as suggested above is your best option.
Good luck and have fun!
Tom
